Answer:
Explanation:
extension in the spring = 40.4 - 31.8 = 8.6 cm = 8.6 x 10⁻² m .
kx = mg
k is spring constant , x is extension , m is mass
k x 8.6 x 10⁻² = 7.52 x 9.8
k = 856.93 N/m
= 857 x 10⁻³ KN /m
b ) Both side is pulled by force of 188 N .
Tension in spring = 188N
kx = T
856.93 x = 188
x = .219.38 m
= 21.938 cm
= 21.9 cm .
length of spring = 31.8 + 21.9
= 53.7 cm .
Answer:
Average speed = 5 m/s
Explanation:
Given the following data;
Distance = 100m
Time = 20 secs
To find the average speed;
Speed = distance/time
Substituting into the formula, we have;
Speed = 100/20
Speed = 5m/s
Therefore, Elsa's average speed is 5 meters per seconds.

I don't really understand the wording of this question but I'd totally cuddle a Koala! If they weren't so mean

Thanks for listening!
Tornadoes are more common in the united states than in the other countries. united states received a total of 1,200 tornadoes annually, four times the amount seen in europe. most tornadoes in the united states occur east of the rocky mountains. the great plains, the midwest, the mississippi valley and the southern united states, are all areas that are vulnerable to tornadoes.
Answer:
current is 13.88 A
Explanation:
given data
no of loops = 50 loops
resistance = 40 Ω
R = 15.0 Ω
I = 5.0 amp
N = 18
to find out
rms current
solution
we will apply here transformed principle that is
v(s) / v(p) = I(p) / I(s) = N(s) / N(p) ....................1
here p is primary and s is secondary
put here all these value
5 / I(s) = 18 / 50
I(s) = 250 /18
I(s) = 13.88
so current is 13.88 A
